1 Hour with @PatrickAlphaC where I cover:
1⃣ how I break down stateful fuzz testing by invariant types and contract lifecycle
2⃣ my favorite general heuristics which I use to find all sorts of bugs in many different codebases
3⃣ mindset and ultimate recipe for success

My X feed has recently degenerated into:
🥇 thirst traps (especially from token2049)
🥈 plague scenarios/theories/doom
🥉 various war/conflict stuff
I don't like any of these posts but X keeps showing them, is there really nothing else more interesting ?

One thing we are seeing in project repos is docs bloat, tons of outdated markdown giving conflicting & stale info to auditors.
Do occasional docs cleanup especially before audit, archive the old stuff make it really easy for auditors to find relevant updated docs 🙏

Starting first full week of Q4 running 7 private audits in parallel, engaging 17 top auditors!
Great mix of audits across EVM, Tempo, Substrate, Solana & Off-Chain!
@cyfrin working harder than ever to help keep our clients safe 🫡

Who is the next Blast according to @grok ?
Last few years saw huge VC alt-chain "gold-rush" but how many alt-chains are generating decent revenue relative to their total raised capital?

I've pushed significant updates to coldclone, a very useful tool for sanitizing foreign repos before engaging with them.
If you're an auditor doing a lot of quoting or a dev downloading new repos to use, running this first is a no-brainer github.com/devdacian/coldclo…

Got first Opus-5.5 safety filter rejections; had 15 PoCs to create but it refused to create 5 sensitive ones.
Opus-5.5 happily wrote up the bugs without PoC so I gave its write-ups to glm-5.3-flash which created the PoCs.
@claudeai cyber safety filters effectively useless 😅

Happy to announce I've accepted an executive position @cyfrin, formally joining the leadership team as Head of Security Research.
We're working harder than ever to keep our clients safe while scaling our private audit business to handle epic demand.
🙏 Blessed 🙏

Crazy how fast AI moves.
2 weeks ago I was driving with Sol-5.6 High (20x) only using Opus-5 (5x) for review.
Now I'm driving with Opus-5.5 High (20x) only using Astra-6 / Sol-6 (5x) for review & just cancelled my personal gpt 20x sub to only use the @cyfrin team sub.

Finishing record Q3 strong this week running 7 private audits in parallel engaging 18 top auditors!
Great mix of protocols for new & returning clients.
Blessed to be working hard every day @cyfrin with top protocols & top auditors, doing our best to help secure web3 🙏

Ethereum Glamsterdam (Q4 2026) finally raises the maximum smart contract size limit from 24KiB to 64KiB.
Huge win for smart contract devs who've been using arcane tricks to stay under the limit while building increasingly complex on-chain protocols.

Capability & techniques for vulnerability discovery have increased exponentially during 2026.
Protocols running $ millions through smart-contracts audited years ago should seriously consider re-auditing asap using the latest techniques.

Opus 5.5 starting to show degraded performance.
Observed historical pattern: Anthropic & OpenAI release new models at full power then sometime during the first week the new models are nerfed.
Still great model but not the same as the first 2 days.

Many new glm-5.3-flash inference providers have sprung up on openrouter.
My top 5 for best balance of performance, speed, reliability & cost are:
1⃣novita
2⃣parasail
3⃣atlas-cloud
4⃣gmicloud
5⃣relace

Q3 new record quarter @cyfrin, blew past prev Q1 record while Q2 was close.
Q4 already Oct heavily booked plus decent Nov bookings, new record incoming.
Private audit demand VERY strong during this bear market year, hardest we've ever worked to help keep our clients safe 🙏

Opus 5.5 is the BEST MODEL IN THE WORLD!
Buy as many Claude Max 20 subscriptions as you can.
Go into debt if you have to.

Drove tooling dev all day using Opus 5.5 High, VERY IMPRESSED.
Clean bug fixes, concise output, no over-architecture or over-complexity, good reasoning through some difficult problems.
Very good model - exact opposite of Opus 5 in every positive way 🫡

Excited to test out Opus 5.5 & GPT 6 Sol/Luna !
Smart & cost-effective models like luna & glm-5.3-flash enable new swarm-based workflows which provide vastly superior performance at a lower price point than was previously possible.

A really cool cross-chain payments protocol that @cyfrin did 5 audits for V1/V2 across EVM/Solana/TRON.
I really liked the use-case of making cross-chain payments extremely simple for people who aren't blockchain natives, abstracting away all the complexity!
Welcome to Atum.
That’s what we tell every new partner when they first touch the network. And now we’re saying it to you.
Because today, @atumhq, the open payments network, a first of its kind, is live.
We picked the date intentionally. Today, September 22, marks the autumnal equinox (in the northern hemisphere), a threshold through which the world passes, from one season into another. Atum occupies a similar boundary: between light and darkness, chaos and order, ending and renewal. Atum, as a platform, is positioned at the transition from closed, institution-specific payment systems to an open, programmable network.
Atum is also the creator god symbol in ancient Egypt. Atum is the first, the primordial, and the originating god of creation.
Atum provides the basic building blocks for payments and commerce - the infrastructure, tooling, products and services that make money move the way it ought to.
Our team is comprised of leading payments and onchain experts from companies like @Visa, @coinbase, @chainlink, @CashApp, @tempo, and more.
It’s a new world for payments and commerce.
And it is my ultimate pleasure, passion, and life’s purpose to introduce Atum, the open payments network. We are so glad you’re here.
Welcome to Atum. We do it together.
